yoctosecond

The smallest MEASURABLE time unit known today, 1x10^(-24) seconds. Obviously, smaller units of time exist, but proper equipment and methodology for measuring them does not yet exist. Light travels 2.9979x10^(-16) meters in one yoctosecond, not the 3.33km stated above.

Learn to multiply. This isn't even an 'urban' word, so why is it defined here?
